Description

For some reason the italian locale has Y-m-d as first choice, the first choice is important because it used as default format in number of places, contrib.admin calendar widget included. Unfortunately we are used to a d/m/Y format so people using the django admin does not feel the format as correct. So reorder DATE_INPUT_FORMATS and DATETIME_INPUT_FORMATS to have d/m/Y as first choice.
Please review. I've added italian localization maintainers in cc list.
